  1. Nashville 8 spots below Atlanta who they thrashed at Regionals.... What has Derbytron been smoking.

  2. Well, the math is obviously flawed (the formulas used) because to have team A, that beat team B TWICE in the past twelve month, ranked 8 spots below them demonstrates that flaw. One or two spots, ok, slight problem, eight spots, something is weighted WAY wrong.

  3. To say that the math is obviously flawed because of one team's ranking is flawed logic.

    Nashville went through a rough stretch where they played very poorly (compared to the rest of their season). Their two games with Atlanta were before and after that stretch. Atlanta played pretty consistently all season. You can definitely argue that Nashville is the better team right now but to mathematically prove that, all of Nashville's games during that rough stretch are going to have to be thrown in the trash. Obviously, you can argue that maybe that should be the case, but then I'm humanly throwing certain games away that I personally think aren't important anymore which isn't the point of these rankings. The point of these is to take the human element out of it.

    You should definitely know that I'm going to update the formula in the offseason to better adjust for certain things and that's probably something I'll look at.

  4. I think one problem is how far back you are looking. To base Atlanta's ranking off 22 games means you are going back well into the 2009 season. In derby world (or really any sports world) that's WAY too long. The Nashville case you mention is a prime example. They start really strong (in 2010). They lose their #2 jammer to season ending knee injury, and they lose 3 starting blockers to other leagues. They then go through a rough patch while B team players get up to speed (that team isn't the team they started they season with). Then as those players come on they rebound (that team isn't the team decimated by losing skaters). It's a bit of a stretch to think results 4 or 5 months old have much bearing on a teams performance today. To think results 16 or 18 months old are any reflection on their current strength pretty much makes zero sense.

  5. Are you aware of how far Flat Track Stats is looking back?

    I know exactly what you're talking about and that's one of the reasons I came up with this rankings system. What you're not realizing is how these ratings are being calculated. I recommend reading the methodology. The games in 2009 are only July and after so every rating on here is less than a year and a half old. Also, the games in 2009 are weighted so little that they account for barely more than nothing for teams who have played many games in 2010 (the reason for using games from 2009 is to be able to rate teams at the beginning of the season when no one has played anybody and for teams that don't play very many games during the entire season). Also, the last 3 games for each team are weighted 167% heavier than games played earlier in the season.

    So, there is definitely an emphasis on the idea of "what have you done lately." Maybe it's not enough, that's a fair assessment.

    But, that Nashville rough patch ended at the end of August against Steel City. That's still pretty damn recent, isn't it? Less than 3 months and 5 games ago.

    It sounds to me like you're saying that only games played within the last 2 months or so should be counted. If that's the case, I think you need to pay a little more attention to how often teams outside the top 25 are playing (and even some teams in the top 25). If I was only ranking teams based on the last 2 months, #1 I'd only being ranking probably half of the teams I am now because there'd be almost no data and #2 the rankings would make absolutely no sense because they'd be based on almost no data.

  6. Okay, so I just did a test where I cleared out all the data from before September.

    That means that there are only 39 teams left that have enough games to be ranked and 9 of those teams are unofficial (having played less than 4 games). So, less than 1/3 of all WFTDA teams would be officially ranked.

    The top 3 is exactly the same and the rest of the top 10 doesn't look super different with the exception of Texas being ranked 4 spots lower. You will be happy to know that Nashville is ranked #20 and Atlanta is #22.

    Not to make excuses because I do want every team to be ranked exactly perfect but the Derbytron did pick correctly 11/12 games at the WFTDA Championship and is pretty much in a dead heat with DNN's Power Rankings at 83.2% in Top 25 games vs. their 83.0% accuracy.

  7. So San Diego is in but Pioneer Valley/Western Mass Destruction who has pummeled the likes of New Hampshire and Hudson Valley doesn't make the list?

    For shame. Like San Diego being banned for not skating enough flat track, we're banned because we have a league that has a mens team.
